Some "How To" wood projects for kids will depend greatly on the age of the child. My suggestions would be: a tool box carrier, a baseball cap rack, a bean bag game board, bird house or bird feeder, and a counting frame. These would all be for the younger child, with help from you. Some patterns for the baseball cap rack can be found at woodworkersworkshop.com. I will do a short Hub to show you pictures of two of these that I have made.
